card: certification status, voided runs, layer-sweep negative result

@@ -56,6 +56,19 @@ are width-1024 — cross-width tensors cannot be weight-averaged. L/14
 (1024-wide, 24 layers, patch 14) is the scale where Core + Spatial + AV-video
 share width/depth/patch, so true weight fusion is possible.
 
+## Status (2026-10-03): this tag is the grid-search winner, still current best
+
+- Evolution rerun in progress after two voided attempts (documented below) —
+  if it certifies a better genome, that becomes the next revision.
+- Layer-depth probe: naive mid-network readout does NOT beat the joint output
+  (t2i R@1 ≤ 0.06 vs 0.79) — mid-network features need trained per-layer
+  pooling (fine-tune phase), not a free readout change.
+- Voided runs: (1) blend-of-blend contamination via shared-storage state_dict;
+  (2) silent no-op `load_state_dict` on this model's dual-prefix key layout;
+  (3) joint-path audio mismatch that faked ESC collapse at high audio weight.
+  All fixed (pristine clones, `copy_` by param name, standalone-tower-only
+  audio mapping) before trusting any evolution number.

 ## How it was built
 
 1. Audio tower: exact-shape suffix-mapped average of AV-audio and A-Frame-audio
